Start or run capacitor? How often does the motor cycle on and off? The biggest enemy of capacitors is heat. If the unit is outside in the summer heat, it's lifetime is much shorter than one inside where the temp is conditioned. So, depending on the factors above, the answer could range anywhere from as short as a year to ten years or more.

What is run capacitor in single phase motor starter with three wire?
A run capacitor and a starter capacitor are not the same thing. A run capacitor is energized the entire time the motor is running, and a start capacitor is not. A run capacitor is one that changes the current on the windings of a single phase AC induction motor to create a rotating magnetic field to energize a second-phase winding. A start capacitor increases starting torque, allowing a motor to be turned on rapidly. It stays in the circuit only long enough to bring the motor to 3/4 of full speed. Some motors then continue to run with a run capacitor.
What is the differencebetween a run capacitor and start capacitor?
The run capacitor is used when the load is functional while the start capacitor is used to produce the initial torque to drive the load.
How do you differentiate a start capacitor from a run capacitor in air conditioner?
If the air conditioner has both, the run capacitor is likely the largest one. The start capacitor will only be in the circuit for a very short time, so overheating doesn't become an issue. The run capacitor must be sized for continual use.
Can you change a 440 volt 12.5 uF start capacitor with a 370 volt 12.5uF run capacitor?
There are two ways to read this: you have a burned-out run capacitor on your motor and a good start capacitor in your parts box, and you have a burned-out start capacitor and a good run capacitor. If the run capacitor's bad and you want to put the higher-voltage start cap in its place, the answer is yes. This is called derating, and the only thing it does for you is increases the lifespan of the capacitor because you're not working it as hard as it can take. If the start capacitor's bad, don't do this--they used a 440-volt capacitor in there for a reason.
How is a run capacitor constructed?
A run capacitor is constructed with wire, wire strippers, cling wrap, scissors, aluminum foil, and cellophane tape. A run capacitor is defined as a unit that stores energy electrostatically in an electric field.

Can you use a run capacitor in place of a start capacitor?
No

What is the basic shape of a start capacitor?
If you mean run capacitor, as in the run capacitor for an AC motor, it is usually a round or oval cylinder.
Do all motors that use capacitors must have at least one run capacitor or a run and start capacitor true or false?
true

How long does a grunion run last?
As long as it takes.
What size capacitor does ducane condensor AC10B48-A?
89M77 40+5MFD-440VAC dual run capacitor
What are the starting and running characteristics of a capacitor-start motor?
Easier to start up. Running remains the same unless it is equipped with a run capacitor too. A run capacitor uses a little less current during run and probably runs a little cooler too.

A run capacitor is constructed with wire, wire strippers, cling wrap, scissors, aluminum foil, and cellophane tape. A run capacitor is defined as a unit that stores energy electrostatically in an electric field.
